Definitions

  • the present invention relates to a modular switchboard terminal block having means for the reception and transmission of optical signals.
  • a plurality of slave elements arranged in the vicinity of the local detection devices 3 and/or peripheral devices to be controlled - such as temperature sensors and/or printers and the like for acquiring/emitting electrical data signals 2 from/to the said devices - and by a further element 4, called master element, which is designed to be connected by means of predefined protocols, e.g. of the Ethernet type, to a data collection and processing device 5 which is normally remote and also to send/receive data signals to/from the slave devices.
  • master element which is designed to be connected by means of predefined protocols, e.g. of the Ethernet type, to a data collection and processing device 5 which is normally remote and also to send/receive data signals to/from the slave devices.
  • these data acquisition/emission elements may be formed as switchboard terminal blocks, that are devices having terminals for connecting with electric wires.
  • connection between the various known terminal blocks is of the electrical type and involves the connection of each of them to a common distribution board by means of special contacts and wiring cables, so-called buses, which give rise to a series of technical problems due to the need to provide the contacts on each element and on the distribution board and also because of their sensitivity to electromagnetic disturbances, which are particularly significant in the case of management of both digital and analog low-voltage data signals.
  • the high number of contacts needed to provide a distributed network therefore gives rise to corresponding high costs for production and management of the different types of contact systems and therefore for storage and distribution, as well as a high probability of transmission errors, due to the said electromagnetic disturbances and mechanical disturbances, and also due to the wear affecting the known terminal blocks.
  • optical connectors for optical fibres and the like which are designed for reception and transmission of optical signals; examples of these devices are for example described in US 2016/0191166 and US 2004/0218288 .
  • the technical problem which is posed therefore is that of providing a modular switchboard terminal block which is able to acquire/distribute data signals, in particular, but not exclusively, for distributed networks and which is able to eliminate the drawbacks of the prior art and in particular the need for a large number of electrical contacts and the sensitivity to electromagnetic and/or mechanical disturbances.
  • this modular terminal block should be able to transmit a power supply, should have small dimensions, be easy and inexpensive to produce and assemble and be able to be easily installed at any user location using normal standardized connection means.
  • a set of three reference axes i.e. in a longitudinal direction X-X of width, transverse direction Y-Y of depth and vertical direction Z-Z of height of the terminal block, as well as a front part A corresponding to the visible part of the modular element and a lateral part for connection of the various modules in the transverse direction Y-Y
  • two modules according to the invention will be described below, i.e. slave module 10 and master module 20, illustrated and described with reference to a preferred embodiment of the modular element realized as a switchboard terminal block designed to be engaged with a DIN rail 6 ( fig.9 ).
  • a slave modular element 10 or master modular element 20 according to the invention comprises:
  • each modular element has electronic circuits comprising a receiver device 33b;34b and a transmitter device 34a,33a of a respective first and second receiver/transmitter pair 33;34, arranged in a predefined position in the vertical direction Z-Z and in opposite directions of the transverse direction Y-Y, for example on each side 30a,30b of the printed circuit 30, so as to define two different directions of propagation of the optical signals from/towards the other slave modular elements 10 and/or master modular elements 20.
  • the side surfaces of the two containing half-shells 10a,20a and closing half-shells 10b,20b have a respective reception window 13 and a respective transmission window 14 in the preferred example shown being respectively formed by openings which are different from each other, for example square and circular.
  • Each slave module 10 and master module 20 further comprises means for electrical connection to adjacent slave/master modules for transmitting the power and earthing sources for power supply of the control circuits; for this purpose ( Fig. 7 ), the printed circuit 30 comprises female connectors accessible from outside the container and suitable for connection to conducting strips 50a of jumpers 50 ( Fig. 3 , 9 ).
  • the insertion of the jumpers 50 in the respective female connector 35 gives rise to both an electrical series connection of two adjacent terminal blocks and a mechanical connection between them, ensuring their stability and rigidity.
  • the female connectors 35 of the printed circuit are provided on different opposite sides of the terminal block so as to define in an unambiguous manner the power line (Volt) and the earth line (GND), thus avoiding connection errors which could result in damaging short-circuits.
  • the electric power supply lines in a position at a distance from the optical transmission lines in the vertical direction Z-Z in order to prevent an eventual interference, cause of disturbances.
  • the master terminal block is designed to generate optical data signals and to transmit by means of a jumper 50 an electric power supply, received for instance from a wire connected to the electrical connector 21, to the single slave modules 10, for powering thereof; these latter are able to receive and process data signals assigned to them and/or forward to other slaves modules the data signals emitted by the master device and not assigned to them and/or transmit an electric power supply to adjacent terminal blocks by means of a jumper.
  • the modules according to the invention which are shown by way of example in the form of a terminal block, have a rear end face provided with hook and spring means for mounting on DIN switchboard rails 6.
  • the switchboard terminal blocks according to the invention for the transmission of data by means of optical signals allow connection together of the various modules by means of simple contact of the respective adjacent side surfaces, said contact bringing the respective optical receiver/transmitter means of each side of the printed circuit into alignment with the transmitter/receiver means of the other module, resulting in two different transmission and reception channels along which the optical signals travel, thus being able to eliminate the drawbacks of the prior art and in particular the need for a large number of electrical contacts.
  • optical transmission modules according to the invention also results in the substantial elimination of the mechanical disturbances resulting from vibrations and electromagnetic disturbances resulting the connector connections of the prior art, having moreover small dimensions, being easy and inexpensive to produce and assemble, not being prone to wear and being able to be installed easily in any user location using normal standardized connection means.
  • each slave module 10 or master module 20 comprises indicators 16,26 for indicating an enable/disabled condition, for example consisting of LEDs which may optionally be differently coloured, for indicating the different condition/state of the module; preferably the indicators are arranged according to different alignments for the master and slave devices.
  • a further advantage arising from the configuration of the modules according to the invention is the elimination of any errors in the connection between adjacent modules; the asymmetrical configuration of the windows 13,14 of the half-shells 10a,10b 20a,20b provides an unambiguous guide for the user.
  • the master terminal block may be arranged on either one of the opposite ends of the DIN rail, but also in an intermediate position between several slave terminal blocks arranged on opposite sides of the master module in the transverse direction Y-Y parallel to which propagation of the optical data signal occurs.
